Thanksgiving Side Dishes, Apps. or Desserts a 10 year old can easily make

This year my 10 year old niece has volunteered to help cook Thanksgiving dinner. While I already have my menu planned, I'm willing to be flexible to accomodate her request. While she can certainly help with various aspects of the recipes I already planned on making, I was wondering if anyone had some great menu ideas that my niece can make/bake virtually on her own that she can then claim was a result of her sole efforts. I remember that many years ago, when my son was little, he took over the corn pudding recipe which subsequently turned into "Gabe's famous corn pudding" on our annual menu. I'd like to do something similar for my niece. Any suggestions for an interesting appetizer, side dish and/or dessert that would work?
